Aircraft state estimation for a ground directed bombing system.
John A Jauregui · Defense Technical Information Center (DTIC) · 1982
The performance of a modified linear Kalman filter with adaptation is compared with that of a common adaptive alpha-beta filter for state estimation of a pilot controlled, ground directed bombing system. Of particular concern, is the accuracy and response of the alternative filters when the aircraft conducts random maneuvers in the vicinity of the target. The desirability of including deterministic forcing in the filter model is discussed and a technique utilizing an adaptive Kalman identifier to establish the pilot response to ground control heading commands is presented.
